<p>A recovery protocol for distributed systems using the time warp control mechanism is described. The proposed protocol is fault tolerant to multiple process failures. Time warp is an optimistic execution technique in which synchronization is achieved using rollback. The recovery protocol exploits the redundancy already available to implement process rollback in the time warp mechanism. Thus, the protocol has little additional bookkeeping overhead, which contrasts with many other recovery protocols.</p>
